Siddharth Seth updated YARN-50:
-------------------------------
Attachment: YARN-50_wip.txt
Work in progress. Some of the classes can be moved to different packages. Needs
to be tested.
One flaw with renewing tokens in their current form in the RM, is that the RM
ends up depending on the token Renewers to be in the classpath.
HDFS token renewal already needs the HDFS renewer (DFSClient.Renewer) to be in
the RM classpath.
With this patch, MR JobHistoryServer token renewal requires MR jars in the RM
classpath. (The patch does not add them - but the default startup scripts
already do). It also ends up requiring HistoryServer configuration parameters
to be part of the RM configuration.
Avoiding these dependencies doesn't seem like it'll be a small change.
> Implement renewal / cancellation of Delegation Tokens
